Are we winning in Iraq?

A few days ago Michael O'Hanlon and Ken Pollock published an Op Ed in the New York Times claiming that we are winning in Iraq. This was based on a brief visit to that godforsaken country.

Today Juan Cole is reporting that July was the deadliest July for US troops since the war began. He also noted that with the largest group of Sunnis pulling out of the government the Maliki government is on the verge of collapse.

I don't think the facts on the ground support what O'Hanlon and Pollock are saying.
